I think it works:

Answer 2

Yes, you need to register PhoneListener with your application and need to implement required methods like:
callInitiated()
callEnded() etc..etc
i.e. whenever particular call gets initiated you can listen that event and execute custom code.
You can use the PhoneCall class to read the call information.
Hope this helps.
